Gonna' be a hot rain.

[mitchnick]

So?

considering temps normally go down with elevation at the rate of 3.5 or 5.5f every 1,000 ft, I find that incredible

[Ian]

we did have a shot at a 1-2" event....that isn't impossible though it seems more improbable than yesterday when the models were showing a much better track.....were you believing in something more than that?....if so shame on you

we had a glimmer of hope but it's not often we get to the final answer 48-60 hours out. the writing was on the wall with this one since it looked interesting imo.

just think if we were going into this with a normal temp regime.. ahh.

I would be ecstatic over 2" and felt that that had a great chance

but admit that the trend was looking so good yesterday that it made me think it had a reasonable chance of becoming a mod event

shame on me again

I wish 09/10 never happened

by the time I get over it, my Will will be in the possession of the Register of Wills

you are an eternal optimist. i remember you comparing october to december 2009 for some reason.

The SI Weather talks about the very impressive upper level feature that could cause thunderstorms during this upcoming event. Also, there is an interesting “bulge” in the 1000-500 mb thickness pattern on the 12Z GFS which suggests a changeover to snow is likely with this strong upper level feature. 1-3 inches likely in the immediate N and W suburbs of DC, Philly and NYC with an inch or less in the big cities. The heaviest axis of snow looks similar to the late October storm (ie eastern WV to south-central PA to the Poconos to interior New England).

Bob,I think it's worse than that

I think it's "welcome to the winter of 11/12"

too many similarities to 10/29 and this storm wrt problems we face and considering the patterns have a tendency to repeat themselves, well, it is what it is for the foreseeable future

otoh, IF we ever get the stratosphere over the pole to cooperate, we could have a monster or two this year

until then, we deal with this

Come on man December just started. We're not getting a favorable large scale pattern in before the end of the month anyways. In a nina if i had to choose a month with a +AO it'd be December not only because that's when most ENSOs peak but also because wavelengths aren't as favorable for us, and they're still changing which makes it hard to get accurate modeling.

[WinterWxLuvr]

Long way to go.

[usedtobe]

after passing overhead

yoda!!!!!

And more importantly, north of me.

as long as people continue to have unrealistic expectations EVERY SINGLE STORM they will be upset with many of the end results.

The trend crept warmer throughout the day yesterday, so I fully expected this to happen. I-95 was already right on the edge of the rain/snow line, two days out, and it was clear that even the slightest warm shift would decimate our chances.

I wish 09/10 never happened

If so, then you're out of your mind.

[mitchnick]

if they would just loosen these d@mn straps, I would be able to type better and explain why

everything was trending north into yesterday.. no reason to think it would magically stop in a good spot for 95 etc. north trend almost always wins especially in a super +NAO. the euro is good but it was not locked in as of yesterday.. so the fact that it snowed on us quite heavily for a run or two was pretty meaningless.

[MN Transplant]

2 hours of snow wouldnt be bad....I was using twister...didn't realize there were hour increment maps...wonder how accurate they are?...I assume they derive directly from model output data?...or are they extrapolated and estimated?

I have no special knowledge, but I assume that it is model output and not interpolation. At 36hrs, it goes to 3 hr increments on the iwm site.

I'd also take the 2-3 hours, especially since it comes with some decent 700 UVVs. No shame in rooting for the small stuff. I missed commutageddon last year, so I've seen about 3" total since Feb '10.

Fozz, you are so rational

why are you here?

This event Wed night/Thursday morning - the rain to light snow episode

1) ELEVATION Dependent !!

2) You must be MUCH, MUCH farther west and north

Application: I'm calm and serene - I'll enjoy my 3-4 inches of plain RAIN. The rain will transition to snow in Dale City - BUT will be ending right about the time the precip manages to change to all snow.

Maybe a coating on the car top but I'm not holding my breath.

You want accumulating snows - Go to Garrett County MD

It's a damn good thing I am so obsessed with Battle Pirates. We have a La Nina with a negative PDO. The heat ridge is raging, as is the subtropical jet.

You all know the drill - Freezing weather, followed by milder, followed by soaking rainfall, followed by freezing weather. Rinse and repeat many times through early May 2012.

I actually find the 10/29 and current track quite interesting. Not really what we're supposed to be seeing in a nina year. Especially with the craptastic overall setup. October had a better pattern than now but I think it's still a bit encouraging in a way to have another similar system.

Last year featured 850's cruising up the oh valley and jumping to the coast. I personally hate those. I'd rather have an 850 rainer moving overhead or to our east than a miller b. People up around the pa/md border probably don't mind miller b's but us dc metro folk already kinda know how those work out. Then when we did get the big block in place it pushed everything too far south but that's not a terrible thing I guess. Just bad luck.

The psu storm was a nice one. Nice dynamic ull with a nice track. If you're not going to have a miller a then give me that over a miler b anyday.

This year has featured 2 nicely place ull's already. With no blocking and no ao we don't get what we want in the end but keep on having shorwaves tracking across the gc and move them n through nc and off the va coast all winter long. I'll take my chances.

We'll see how things shape up later this month. I'm still optimistic about near climo snow this year and won't change my mind unless the +ao/nao combo is locked into place as we move into jan.

[Ian]

18z gfs looks pretty similar to 12z.. a bit lower qpf which should probably be expected

[WVclimo]

9 runs in a row showing WSW criteria snowfall for here, between the GFS (Sunday) and NAM (Monday and today's 12Z).

18Z NAM: 0.0"

[SeanVA]

My best guess at what's gonna go down.

now that really sux

I would think it would change however

Nice map -- especially since you consider the ridges out this way.

[Ian]

verbatim we get ~2hrs of snow falling at some temperature above freezing onto puddles of rain.....Are we looking at one decent band you think?.....or totally nonaccumulating?

I would think there's some superband potential with the s/w as it passes by. I was looking to see how close the oct one was to us but could not find a good image. I think it went almost overhead. As far as accum.. we need a good band or probably not. Even then, very little.

I have a feeling the superband will be more like the movie superbad .

In all honesty though...you're probably right. I'm expecting a few flakes at the tail end. Lots of rain though! Grab the boats!

RLX staying conservative on amounts even in the mountains...saying no accumulation down here in the western lowlands. Local TV mets going 1 - 3" here and up through central WV though they think it will shift more west...

[Yeoman]

I don't think Yeoman has actually added to the conversation in a few years here so don't worry about him too much.

Life always gets in the way

Thanks, I have been paying a lot more attention to elevation recently after moving out here and getting a Snowshoe season pass haha
